Abstract

Quadrature index spatial modulation (QISM) with two constellations is presented to exploit the potential spatial diversity gain from spatial domain in multiple input multiple output (MIMO) channel system. In this paper, we consider a transmitted spatial vector formed by mapping two constellations symbol from BPSK and M-ary quadrature amplitude modulation (M-QAM/PSK) on the MIMO antenna array operating over Rayleigh fading channels and in the presence of additive white Gaussian noise. As a result, minimum Euclidean distance (MED) between the transmitted spatial vector in QISM scheme has a bigger spatial distance than that of quadrature spatial modulation (QSM). Then the bit error rate (BER) performance of QISM is analyzed. In addition, performance comparisons between spatial modulation (SM), QSM, QISM schemes for the different spectral efficiency are presented. The results demonstrate that our proposed scheme achieves the robust to the reliability in wireless communication network.
